Specification of Letters Patent.

Patented Jan. 4, 1916.

Application led August 20, 1914. Serial No. 857,720.

To all whom it may concern:

Be it known that I, WILLIAM F. Kmsnr., J r., a citizen of the UnitedStates, andvresident of Altoona, Blair county, State of Pennsylvania,have invented certain new and useful Improvements in Locomotives, ofwhich the following is a specification.

My invention relates to locomotives of that type wherein the power usedto rotate the driving wheels is transmitted to and through a jack shaftwhich is positioned between the prime mover and driving wheels.

Heretofofe it has been customary to make the bearing for the jack shaftsimilar to the bearings for the driving axles so that the jack shaftcould be dropped downward into a pit by removing the frame strap underneath the journal box and dropping 1t out of the box.

My invention contemplates a jack shaft" ypositioned transversely torotate in bearings at eithery of the locomotive andl adapted v end, thebearings being rigidly fixed-1n the lframe of the locomotive and havingmeans whereby the jack shaft crank can be readily placed in position andremoved without the usual difficulties associated with this type of'power transmission device.

d The above and other objects and the novel features of my inventionwill be apparent from the following description, taken .in connectionwith the drawings, in which:

Figure l is a side elevation of substantially one-half of an electriclocomotive'embodying my invention; Fig. 2 is an enlarged detail viewpartly in section showing the manner of mounting the jack shaft on theframe; and Fig. 3 is an end elevation of the parts shown in Fig. 2. l

Referring to the drawings, and particularly Fig. 1, each half of theelectric locomotive or engine consists of a parallel frame members 10and 11 about 34 long, two pairs of driving wheels 12 and 13 mounted onthe axles 14 and' 15, two pony trucks comprising the pairs of pony truckwheels 16 and 17 mounted on the pony truck axles 18 and 19, and a jackshaft 20 between and substantially in line with the.,axles 14 and 15 andcarrying two gear wheels 21 and 22 into which the pairso of pinions 23and 24 on the axles of the motors 25 and 26 mesh. Each ofthe gear wheels21-and '22 is connected by suitably located connecting rods 27 and 28with the pairs of driving wheels 12 and-13 respectively..

feet 6 inches The bearings-for the jack shaft 20 consistl of circularholes 29 and 30 in the frame members 10 and 11 respectively into whichthe phosphor bronze bearing sleeves 31 are pressed. The bearing sleeves31 are provided at one end with" exterior flanges 32 to limit theirinwardmovement. For the purpose of keeping the bearing sleeves 31 fromrotating a plurality of bearing anchor bolts 33 are-provided and arepreferably located on thel underside thereof having the Shanks extendingthrough the bearing and the heads countersunk therein with the securingbolts bearing against the underside of the .frame members. The faces ofthe journals adapted to engage the inner surfaces of the bearinglsleeves 31 are, in this construction, formed integral with the cranklocated on the jack shaft. The cranks in this conhubs 34, the exteriorsurfaces of which are designed to iit the interior of the -hearingsleeves 31 and are enlarged at their bases as at 3,5 to engage theflanges 32 on the; sleeves and space the gear wheels 21 and 2,2ffrom theframe members 10 and 11 respectively. The gear wheel hubs slide freelyIin the phosphor bronze sleeves which provide a suitable bearing for thegear wheels and the jack shaft 20 which is secured thereto.

The hollow hubs 34 have tapering axial openings therein to receive andfit the tapering ends 36 of the jack shaft 20. The jack shaft 20 passesthrough the wheel hubs and the ends thereof are threaded to receive thenuts 37, whereby the wheels are held to the shaft on the outside of thewheel center and 'thus the bearings on the inside of the wheels treatingthe shaft a longitudinal hole 40 is drilled through the same, the endsof which -are preferably plugged after the shaft is reassembled.

' The phosphor bronze bearing sleeves 30 are solid, ,that is, they arenot cut in halves andif theywear considerably they maybe A replaced' bynew ones after first withdrawing the gear wheels. This arrangement makesit easier to keep the shaft 20 in proper alinement and makes it no moredifficult to replace the bearings. In case it is necessary to removeeither of the gear wheels this can readily be done by first removing theadjacent side-motion spring 41, then removing the nut 37 and drawing outthe wheel. The opposite wheel with the shaft 20 may readily be pulledout from the other side. Since there are no torsional strainstransferred through the jack shaft 20, it is not necessary to providethe shaft and gear wheels with keys, which arrangement is commonly foundin prior constructions of this type.

For the purpose of supplying lubricant to the bearing surfacesbetw'eenthe sleeves 31 and the hubs 34, an oil reservoir `42 is provided on theinner side of eacliof the frame `members 10 and 11 directly above theopenl ing therein and is preferably made integral with the frame. Eachof the lubricant containers 42 has a filling opening 43 for filling thereservoir from the outside of the frame and a larger opening 44 on theinside for filling the reservoir from the inside of the frame and forcleaning it out. Duets 45 extend through the bottom of the reservoir andregister with perforations 46 in the bearing sleeves 31 to lead thelubricant to a recess 47 on the inner surface of the bearing sleeves 31and at the top thereof between the said bearing sleeves and the hollowhubs 34 on the gear wheels.

The cab 48, one-half of which is shown in outline in F ig. 1, is securedand rests on the body bolster 49. The body bolster 49 has a pair ofextensions 50 at each of its ends andl the underside of each extensionis. provided with a lug 51 which fits the top surface of the side-motionspring 41 which rests in a saddle 52. The saddles 52 at each side of thetruck aremounted at the ends of the truck bolster 53 which is supportedby the side frame members 10 and 11. y

The particular cab supporting arrangement herein shown is made thesubject-matter of a separate application.
